LINEN BUTTON.

SPECIFICATION forming part of Letters Patent No. 748,287, dated December 29, 1903. Application filed. May 2, 1903. belial No. 155,433. (to model.)

To aZZ whom it may concern:

Be it known that I, HERMANN KIRoHHoFF, a subject of the Emperor of Austria-Hum gary, residing in the city of Barmen, Rhenish Prussia, Empire of Germany, have invented a new and useful Improvement in Linen Buttons, of which the following is a specification.

Myinvention has for its object a linen button which has the property of being hard when it is dry and flexible when in a wet state, so that the button is infrangible.

Figure 1 is a top view of the button. 2 is a section thereof.

The new button consists of a core a, a textile or fibrous material or a weaving, felt, or the like which is impregnated with animal albumen. By coagulating the albumen, material will be attained that the button in a dry state is perfectly hard, but in wet state or when moistened has a high elasticity, so that it may be washed, boiled, wringed, calendered for cleaning and other purposes without breaking or being altered in its shape. When dried, the button assumes Fig.

again its hard state and its original appearance.

This button may be fitted with a lining b, of the material described, which is also im- I claim, and wish to secure by Letters Patent,

l. Alinen button consisting of afibrous or textile material impregnated with animal albumen for the purpose described and set forth.

2. A button consisting of a fibrous or textile material impregnated-with animal albumen said button having a lining of any textile material impregnated with animal albumen and united with the body of the button for the purpose described and set forth.
